Right Angles

A right angle is an angle that measures exactly 90 degrees. It looks like the corner of a square or the letter "L". When two lines meet at a right angle, they form a perfect square corner. Right angles are denoted by a small square at the angle point.

In geometry, we use the symbol ∟ to represent a right angle. When two line segments or rays meet to form a right angle, we say that they are perpendicular to each other. Perpendicular lines form four right angles where they meet.

Right angles are found all around us, from the corners of buildings to the hands of a clock at 3 o'clock. Understanding right angles is important in geometry, architecture, and everyday measurements.

It's important for students to be able to recognize and identify right angles, as well as understand their properties and applications in various fields.

Overall, right angles are a fundamental concept in geometry and an important building block for understanding the properties of angles and shapes.
